Figure 7 is a side view on reduced scale of a punch press showing ourimproved jig filling mechanism applied thereto.

Figure 8 is a rear view of the same.

This invention is applicable to machines for making articles of varioussorts that are afterward subjected to other operations for the purposeof finishing or for assembling them with other devices to completestructures of which the articles constitute a part, and while theinvention is not limited in its use to machines of any particular type,as it is readily adapted for operation in connection with a punch pressfor producing articles from sheet metal, such a machine has beenselected for the purpose of illustration and description of theinvention herein, only so much of a punch press, however, as isnecessary to a clear understanding of the invention, being shown in theaccompanying drawings.

In such drawings the numeral 10 denotes geneally the lower part of theframe of a punch press that may be of any ordinary type of constructionand including a die bed 11 having guideways to receive guides 12projecting from a plunger 13 that may be supported on the frame foroperation in any ordinary manner. The die bed supports a die formed withmatrices therein that operate in connection with punches 14 projectingfrom the plunger, and as shown in Figures 1 and 3 of the drawings. Anyordinary and well-known mechanism may be employed for feeding a strip 15of sheet metal across the die bed underneath the punches, as will bereadily understood by those skilled in the art. The punches in theparticular form of machine disclosed herein are arranged in sets, eachset operating on a line extending lengthwise of the sheet wherebyseveral devices, eight in the illustration herein, are produced across asheet, which sheet is eventually cut lengthwise as well as crosswise toseparate the several devices from the sheet as they are formed.

A jig supporting frame is secured to the punch press frame 10 as bymeans of bars 16 secured to opposite sides of the frame in any ordinarymanner and projecting therefrom to locate said jig supporting frame inthe path of movement of the strip or sheet 15 of metal, as shown inFigure 1 of the drawings. This jig supporting frame includes posts 17 inits structure which are bolted to the bars 16 and which extend in adirection substantially at right angles to the plane of movement of thestrip or sheet 15. Said posts are rigidly connected as by tie bars 18located as may be desired and secured in place as by means of bolts.Shoulders 19 are formed on the inner sides of the posts to constituteguideways for a jig carrying frame comprising side bars 20 united at thetop bars 21. A shelf 22 is secured to the bottom cross bar 21 to supportjigs that are placed with their lower ends resting upon said shelf. Aratchet bar 23 is secured to each side edge of the jig carrying frame asa part thereof, said bars being provided with ratchet teeth that areengaged by pawls 24 pivotally mounted on blocks 25 secured to pawloperating levers 26 pivotally attached at their ends to the jigsupporting frame on opposite sides thereof, the opposite ends of saidlevers being connected by links 27 with the plunger 13, and as shown inFigure 1 of the drawings. Retaining pawls 28 are pivotally mounted onstraps 29 secured to the sides of the jig supporting frame, and as shownin Figure 1 of the drawings, there preferably being two of theseretaining pawls on each of the opposite sides of the jig supportingframe and also on opposite sides of the jig feeding pawls 24, all ofsaid pawls being spring engaged with the teeth of the ratchet bars 23.

The shelf 22 on the jig carrying frame receives the lower end of jigsthat are set thereon, each of these jigs comprising a back plate 30 andclips 31 arranged on the face of the back plate and projectingtherefrom, each clip terminating at its outer end in fingers 32, whichfingers and clips are arranged to receive and retain the devices as theyare pushed into the spaces between the fingers in the operation of thepress.

In the illustration shown herein the machine is equipped for makingradiating fins which are attached to tubes and which are employed inapparatus for changing the temperatures of liquids, etc., and, ashereinbefore stated, several of these devices are formed widthwise ofthe sheet or strip 15, mechanism being provided for slitting the sheetlengthwise and for cutting it crosswise to produce said fins. Thismechanism embodies rocker cams 33 pivotally mounted in a cuttersupporting frame 34' which frame is secured to the machine frame 10 inany suitable manner. These rocker cams are supported as upon pivots 35projecting from the frame and as shown in Figure 4 of the drawings. Therockers are actuated as by means of studs 36 that constitute theconnections between the bars '26 and the links 27, said links in thestructure herein shown being forked to receive the rockers in the spacesbetween the branches of the forks. The cutter supporting frame ismounted upon and secured to a die bed plate 37, and upon a lip formed atthe forward edge of said plate, and as shown in Figure 1 and 3 of thedrawings.

A lower cutter frame is mounted for vertical reciprocating movement inthe frame 34, this lower cutter frame being of U-shape as to its endsand comprising a front plate 38, back pieces 39 at each end, and abottom cross-piece 40 at each end of and preferably integral with thefront plate and connecting the front plate and back pieces at the bottomthereof, together with blocks 41 connecting the front plate and backpieces at their ends at the top of the frame.

A cutter blade is secured to the front plate 38 as by means of screws,as shown in Figure 5 of the drawings, this cutter blade being dividedinto sections forming cutters 42 with their edges inclined upwardly fromone edge to the other edge thereof to provide a shearing cut.

a A lower slitting frame is positioned between the front plate 38 andback pieces 39 of the lower cutter frame, this slitting frame comprisinga bar 43 including a block 45 at each end. The bar 43 is supported overa cutter die bed 44 mounted upon the lip at the front of the die bedplate 37 and between the ends of the cutter supporting frame 34. The bar43 is formed with crosswise grooves at intervals along its length, theprojections between said grooves constituting rests 46 for the strip 15of stock. Stripper blocks 47 are located in the grooves and have shanksprojecting through holes from the grooves to the bottom of said bar 43,as shown in Figures 3 and 4 of the drawings. Headed holder rods 43project through the stripper blocks and are threaded into the cutter diebed as a means of retaining the blocks in position. Pins 49 extend fromthe upper surfaces of the rests 46 downwardly through the bar 43, saidpins being threaded into a retaining strip 50 projecting lengthwisealong a groove in the bottom of the bar 43. Grooves 5152 are formed inthe upper ends of the projections and stripper blocks, re-

spectively, for a purpose to be hereinafter described.

The end of each of the projections from the bar 43 constitutes the malemember of a cutting die, each of the ribs created by the grooves 51 insaid end being formed as a cutter 53, the outside edge of eachcutterbeing the cutting edge. of these cutter dies cooperates with afemale cutter member to be hereinafter described. The

Each

lower cutter frame has studs 54 projecting from opposite ends withrollers thereon projecting into cam grooves 55 in each of the rockerearns 33, and the bar 43 with its blocks 45 has studs 56 with rollersthereon located in cam grooves in the rocker cams 33 and as shown inFigures 1 and 5 of the drawings. The cam grooves 55 lift the lowercutter frame into operative position, and the grooves 5'7 move theslitting frame independently of said cutter frame to effect slittingoperations on the strip or sheet of metal 15. The lifting of the lowercutter frame also lifts the cutters 42 which thereby operate to cut theseveral fins 58 from the end of the strip, the front upper edges of theprojections from the bar 43 and of the stripper blocks 47 being formedto cooperate in this cutting action.

An upper cutter frame is mounted in a U- shaped housing 59 comprisingthe top of the cutter frame 34, said cutter frame including a cutter bar60 formed in a manner similar to the cutter bar 43, that is, withcrosswise grooves and projections, the projections in the bar 60 beinglocated opposite the grooves in the bar 43. The grooves in the bar 60contain strippers 61 having shanks extending through the bar and securedto the top of the housing 59, as by means of nuts, as shown in Figure 4of the drawings. This upper cutter frame and particularly the bar 60cooperates with the cutters 42 to separate the fins 58 from the forwardend of the strip 15.

Pins 62 extend through the projections in the cutter bar, said pinsbeing secured in a retaining strip 63 located in a groove extendinglengthwise of the cutter bar and in a manner similar to that withrespect to the cutter bar 43. The projections on the bar 60 constitutecutter members cooperating with the cutter members hereinbeforedescribed on the bar 43, opposite edges of projections on the bar 60being formed as cutters in a manner similar to that with respect to thebar 43, the projections on the bar 60 constituting the male members ofcutter dies entering the grooves in the bar 43, and the projections onthe bar 43 constituting the male members of cutter dies entering thegrooves in the bar 60 as hereinbefore referred to.

Guide rods 64 secured at opposite ends to the die bed 44 and frame 34pass through the cutter frames hereinbefore described to guide thelatter in their movements. The bar 60 has a block at each end similar tothe blocks 45 in the bar 43, and studs 65 with rollers thereon projectfrom opposite ends of the bar 60 into cam slots 66 in the rocker earns33, and as shown in Figure 1 of the drawings.

In the operation of the device the strip or sheet 15 is fed forward sothat its front edge is just within the spaces between the fingers 32 ofthe clips 31, the fins 58 being moved fully into the spaces between thefingers by means of inserting rods 6'7, secured to a rocker bar 68rotatably mounted in bearings in the ends of bars 69 secured in recessesin the back of the front plate 38, and as shown in Figure 6 of thedrawings. There is an inserting rod appurtenant to each row of finsbeing produced lengthwise along the sheet 15, and the rods rest ingrooves in said plate.

The inserting fingers are actuated by means of an inserting cam 70projecting from the front of the die bed 44, said cam being located inthe path of movement of a cam hub '71 on the bar 68. As the cutter frameis moved upwardly by the action of the rocker cams 33 the upper ends ofthe rods 67 enter the holes in the fins 58 at the ends of the sheet orstrip 15. After the ends of said rods have entered the holes the hub 71encounters the cam rocking the bar 63 and moving the upper ends of therods forward, this forward movement taking place just after the finshave been severed by the cutters 42. Upward movement of the bar 68engages a shouldered lip on a hub 72 on the bar with a spring actuatedholder 73 having a stem projecting into a recess at the bottom edge ofthe front plate 38, moving the said holder upwardly against the tensionof its spring. As the bar 68 is rocked to move the upper ends of therods 67 with the fins engaged therewith forwardly into the fingers 32said shouldered lip on the hub 72 is disengaged from the holder 73 andthe latter moves downwardly against the side of said hub thereby holdingthe bar 68 with the upper ends of the rods 67 in their forward positionsuntil the cutter frame has moved downwardly sufficiently to disengagethe rods 67 from the holes in the fins, at which time the holder 73engages a stop 74 thereby arresting its downward movement. The cutterframe, however, continues its downward movement carrying the bar 68 andthe hub 72 away from the holder 73, and as soon as the lip on the hubpasses below the holder 73 the bar 68 is rocked inwardly, as by a spring75 and as shown in Figure 4 of the drawings, carrying the upper ends ofthe rods 67 into position for engagement with the holes in the next rowof fins in the sheet 15.

In making the fins a flange 76 is formed about each hole in the fins,punches 7? cooperating with dies 78 located within openings in the dieplate 79 to break the metal downwardly at the edge of the holes as shownat 80 in Figure 5. In order to permit forward movement of the strip orsheet 15 after the metal has been forced downwardly into the dies '78provision is made for movement of said dies by mounting them on a diebar 81 vertically movable between guide plates 82 secured within agroove cut lengthwise through the die bed 11, and as shown in Figures 3and 5 of the drawings. Studs 83 with rollers thereon project fromopposite ends of the bar 81 into cam slots 84. formed in members 85 ofdie bar actuators. Each of these actuators comprises the member 85 and amember 86 adjustably connected as by means of a holding screw 87projecting from one member into a slot in the other member, and as shownin Figure 5 of the drawings. An adjusting screw 88 is employed to adjustthe relative posi tions between the two members. Both members of eachactuator are mounted upon a pivot 89 projecting from one side of the diebed 11, and a stud 90 with a roller thereon projects from each of themembers 86 into a slot 91 in one of the rockers 33. The rockers 33operate to swing said actuators on their pivots and in this swingingmovement the slots 84 engaging the studs 83 operate to impart verticalmovement to the bar 81.

From this it may be observed that the engagement of the rockers with thestuds from the cutter and slitting frames and from the die bar 81 causessaid members to be relatively movably mounted in timed relation toeffect the different operations required of them in forming the flangedholes in the fins, in slitting the sheet 15 to partially form the fins,and in cutting the sheet crosswise to separate the fins. In the forwardmovement of the sheet or strip 15 the flanges 76, after the dies 78 havebeen moved downwardly and disengaged from the fins, are moved throughgrooves 92 in the die plate 79 and the grooves 51-52 in the projectionsand strippers on the bar 43 hereinbefore referred to.

As the rocker earns 83 are swung from the position shown in Figure 1 bythe downward movement of the plunger 13 the cam slots 57 and 66 operateon the studs 56 and 65 to move the upper and lower cutter bars 43 and 60toward each other, but the shapes of the cam slots 55 retain the cutterbar frame momentarily from movement, vertical movement of this lowercutter frame, however, taking place following that of the upper andlower cutter bars so that the ends of the strip 15 are severed justafter said bars have operated to slit the strip to partially form theseveral fins. The studs 83 and 90 with their cam slots operate to raisethe bar 81 to operatively position the dies 78 at the same time that theplunger 13 moves downwardly and vice versa to move the dies from thepath of movement of the flanges 80 formed in the strip of metal afterwhich said flanges pass along the grooves 92.

As has hereinbefore been stated this machine is particularly equippedfor making radiating fins to be attached to tubes employed in apparatusfor changing temperatures of fluids and we have particularly had in viewin the development of this machine such arrangement that the fins willbe deposited in the jigs in series with intervals between the series,these intervals affording a space in which to bend the tubes inconstructing such apparatus, the tubes being inserted through holes inthe fins while in the jigs and the fins being thus properly positionedon the tubes, the latter are expanded to secure the fins in place afterwhich the fins thus secured to the tubes are removed from the jigs.

In effecting this purpose we provide means for automatically stoppingthe operation of the machine after a predetermined number of finsconstituting a series have been deposited in each row in the jigs. Theoperator of the machine then adjusts the carrier on which the jig restsfor the deposit of the next series, and so on until the jig is filled,after which a new jig is placed on the carrier and the operation isrepeated, the treadle usually employed for starting and stopping themachine being made use of by us in this operation.

Said treadle 93 is of any ordinary type, being pivotally mounted in thebase of the standard 94 and connected by means not herein shown with aclutch mechanism on a driving shaft 95 in a manner well understood bythose skilled in the operation of punch presses, and for which reason afull and detailed description is omitted herein, it being suflicient tostate that when the treadle rises under the pull of a spring 96 theclutch is disconnected and the operation of the press ceases. Thistreadle is held in its lowermost position for operation of the press bya pivotally mounted latch 97 having a shoulder 98 to engage the upperedge of the treadle to hold it depressed, said latch being mounted on aguide plate 99 secured to one of the posts 17, and as shown in Figures 7and 8 of the drawings. Said guide plate has a slot through which thetreadle projects and the latch is spring pressed into engagement withthe treadle.

A trip rod 100 is mounted in guides arranged at intervals along one ofthe posts 17, a latch actuator 101 in the form of a collar being securedto said rod to underlie an end of the latch and as shown in Figure 8. Atripper 102 is adjustably secured to the rod 100 and trip plates 103 areadjustably secured in slots in the back of the side bars 20 of thecarrier. In the structure herein shown this tripper is in the form of ablock containing'a spring pressed plunger the end of which engages theplates 103 and as shown in Figure 3 of the drawings.

A pawl disconnecting bail 104 is pivotally secured to the posts 17 andextends across the back of the frame, as shown in Figure 8, this bailbeing located opposite and adjacent to pawl disconnecting rods 105pivotally attached at their upper ends to the posts 1'? and having pawlactuating rods 106 connecting the rods 105 with each of the pawls thatis engaged with the ratchet bar 23 hereinbefore referred to. A cord 107secured to the upper end of the carrier passes over a sheave 108 at thetop of the frame, a handle 109 being secured to the free end of the cordas a means for manual operation of the carrier.

In the operation of the feed mechanism the starting position of the jigcarrier is at the lowermost limit of its movement and resting against astop 110. The tripper 102 is set to be encountered by the highesttripper plate 103 on the carrier when a predetermined number of finsconstituting the first set have been deposited by the action of thepress, the carrier being moved upwardly a one-step movement in eachoperation of the press. The engagement of said tripping plate with thetripper moves the rod 160 upwardly operating the latch 97 to withdraw itfrom engagement with the treadle 93 and the latter moving upwardly underthe pull of the spring 96 operates the clutch to disconnect the clutchmembers and stop operation of the press.

The press operator now grasps the handle 199 with one hand and with theother hand presses a positioning detent 111 inwardly into the path ofmovement of positioning plates 112, a number of which may be adjustablysecured in slots extending along the back of a side member of thecarrier, and as shown in Figure 8 of the drawings. These plates will beso placed that when one of them strikes the detent 111, thereby stoppingthe upward movement of the carrier, effected by the operator pulling onthe cord 10'? by means of the handle 109, the proper space or intervalwill be created between the last fin deposited in the last series orsets of fins and the first fin of the next succeeding series or sets tobe deposited in the jig. These operations will continue until the jig isfilled. The jig is now removed, the handle 109 is grasped by theoperator, the bail 104 is pushed inwardly, disengaging all of the pawlsfrom the ratchet bar 23, and the carrier is lowered against the stop 110and a fresh jig is placed in position for a repetition of the operation.

In accordance with the provisions of the patent statutes we havedescribed the principles of operation of our invention, together withthe device which we now consider to represent the best embodimentthereof; but we desire to have it understood that the device shown isonly illustrative, and that the invention may be carried out by othermeans and applied to uses other than those above set out.
